Our stretchy, ultralight merino blend beanie for warm-weather performance, the Merino Blend 125 Cool-Lite™ Sphere Beanie features soft, breathable and naturally odour-resistant Cool-Lite™ jersey fabric. Soft merino wool fibres and TENCEL™ Lyocell, a cellulose-based fibre derived from sustainable (FSC-certified) wood sources, combine to create icebreaker Cool-Lite™: a lightweight, breathable and quick drying fabric. Inspired by nature, icebreaker harnesses the performance qualities of natural fibres to offer an alternative to clothing based on petrochemical synthetics.
